1. A communication method, comprising:
within a first discontinuous reception (DRX) cycle, starting, bya terminal device, a first timer when a physical downlink control channel (PDCCH) indicates a new transmission; and
receiving, by the terminal device at a moment before the first timer expires, an indication signal used to indicate the terminal device to sleep, wherein the moment is configured by a network device for the terminal device;
wherein the method further comprises:
skipping, by the terminal device, listening to the PDCCH from the moment at which the indication signal is received to a moment at which an active time of a second DRX cycle following the first DRX cycle ends;
skipping, by the terminal device, listening to the PDCCH in an active time of a second DRX cycle following the first DRX cycle;
skipping, by the terminal device, listening to the PDCCH from a moment at which the first timer expires to a moment at which an active time of a second DRX cycle following the first DRX cycle ends; or
skipping, by the terminal device, listening to the PDCCH from a moment at which an active time of a second DRX cycle following the first DRX cycle starts to a moment at which the first timer expires, wherein:
the first timer expires after the active time of the second DRX cycle starts and before the active time of the second DRX cycle ends, or the first timer expires after the active time of the second DRX cycle ends; and
wherein the method further comprises:
when the first timer expires after the active time of the second DRX cycle starts and before the active time of the second DRX cycle ends, skipping, by the terminal device, listening to the PDCCH from the moment at which the indication signal is received to the moment at which the active time of the second DRX cycle ends, and stopping, by the terminal device, timing of the first timer when the active time of the second DRX cycle starts;
when the first timer expires after the active time of the second DRX cycle starts and before the active time of the second DRX cycle ends, skipping, by the terminal device, listening to the PDCCH in the active time of the second DRX cycle, and stopping, by the terminal device, timing of the first timer when the active time of the second DRX cycle starts;
when the first timer expires after the active time of the second DRX cycle ends, skipping, by the terminal device, listening to the PDCCH from the moment at which the indication signal is received to the moment at which the active time of the second DRX cycle ends, and stopping, by the terminal device, timing of the first timer when the active time of the second DRX cycle starts; or
when the first timer expires after the active time of the second DRX cycle following ends, skipping, by the terminal device, listening to the PDCCH from the moment at which the indication signal is received to the moment at which the first timer expires, and stopping, by the terminal device, timing of a second timer, wherein the second timer is used for timing an active time of a DRX cycle.
